Effects of Painful Compared to Painless Manual Therapy on Pain Processing in University Students With Neck Pain

"* Postero-anterior mobilizations: the physiotherapist will place his thumbs on the posterior surface of the spinous process of the vertebra previously assessed as the most painful to mobilise. The oscillations will be performed at the frequency of 1 oscillation per second and will be performed 3 series of 3 minutes, with a 1 minute rest interval.~* Pressure: The point of greatest pain shall be treated by maintained pressure in each of the following areas: right upper trapezius, left upper trapezius, right paravertebral musculature and left paravertebral musculature. Pressure shall be applied to each of the points for 1 minute.~* Massage: Pressure is applied to the muscles by sliding along the muscle belly. This will be done slowly to control the pain that is being provoked. 3 minutes will be carried out on each upper trapezius, sliding from the acromion to the occipital and another 3 minutes on the paravertebral musculature on each side, sliding from T1 to the occipital."
